FS location for 3rd party modules?

[Jakub Hrozek]

Hi,

starting with sssd 1.8 we are going to support two third party applications -
sudo and autofs. In both cases we are going to provide a library these
applications would use to communicate with SSSD.

My question is what is the best place to put these libraries to? I
would suggest /usr/lib{,64}/sssd/apps or /usr/lib{,64}/sssd/modules and
name the libraries something like libsss_$appname.so (libsss_sudo.so,
libsss_autofs.so, etc.)

I don't think we should install the libraries into the hierarchy owned
by the applications themselves (i.e. /usr/lib{,64}/autofs for example),
I think it should be inside SSSD directories.

Comments are appreciated.

This is probably the best choice. I can't think of a more appropriate location.

Is it our call ?

We do place our memberof.so plugin in /usr/lib/ldb because that's where
ldb looks for. So you should ask sudo and autofs projects where they
plan to look for plugins or if they will provide configuration options
to point at arbitrary locations in the file system within their config
files that we can then set.

Simo.

Sorry, I forgot to answer this mail. 

Sure, I did ask and the reply was "whenever you like as long as the
location plays nice with packaging guidelines".

Patches are on the list now.
